Fisher™ FIELDVUE™ DVC6200 SIS Digital
Valve Controller for Safety Instrumented
Systems (SIS)
The FIELDVUE DVC6200 SIS digital valve controller is a
HARTr communicating instrument for use in valve
applications such as Emergency Shutdown, Emergency
Blow Down, Emergency Venting, and Emergency
Isolation. The DVC6200 SIS is capable of monitoring
the health of and controlling the safety shutdown
function of a valve and can easily be installed on most
Fisher and non‐Fisher pneumatic actuators.
Features
Reliability
n Linkage‐less Position Feedback—The high
performance, linkage‐less feedback system
eliminates physical contact between the valve stem
and the DVC6200 SIS. This minimizes the affects of
pipeline vibration and environmental corrosion.
n Built to Survive—The field proven DVC6200 SIS
instrument has fully encapsulated electronics that
resist the effects of vibration, temperature, and
corrosive atmospheres. A weather‐tight wiring
terminal box isolates field wiring connections from
other areas of the instrument.
Safety
n Partial Stroke Testing (PST)—This is a small ramp
test that moves the valve, without disrupting the
process, to detect a stuck valve. Testing can be
automated, or manually initiated with an external
pushbutton or Fisher LCP100 Local Control Panel.
n Full Stroke Testing (FST)—This is a full ramp over the
entire valve travel range that is typically performed
during a shut down. This test can reveal failures
undetected by the PST on-line diagnostic testing.

Ease of Use
n Remote Access—The DVC6200 SIS is a HART
communicating device, so information can be
accessed anywhere along the loop. This flexibility
can reduce exposure to hazardous environments
and make it easier to evaluate valves in hard to
reach locations.
n Faster Commissioning—HART communication
allows you to quickly commission loops with a
variety of tools, either locally at the valve assembly
or remotely.
n Easy Maintenance—The DVC6200 SIS digital valve
controller is modular in design. Critical working
components can be replaced without removing
field wiring or pneumatic tubing.
Value
n Spurious Trip Protection—PST Pressure Limit defines
the output pressure threshold that will abort the
partial stroke test if exceeded. This prevents the
actuator from completely exhausting pressure and
potentially causing a spurious trip in a sticking valve
scenario.

n Increased Uptime—The self‐diagnostic capability of
the DVC6200 SIS provides valve availability and
health evaluation without shutting down the
process or pulling the valve assembly from the line.
n Audit Documentation—Using ValveLink™ software,
a time and date stamp on all tests and reports
provides compliance with requirements of statutory
authorities.

Packaged Solutions
LCP100—A local control panel can be connected
directly to the DVC6200 SIS to provide manual control
of the SIS valve, including manual reset. A partial
stroke test can also be initiated with the LCP100
(see figure 1).
Figure 1. Fisher LCP100 Local Control Panel
n Hardware Savings—When installed in an integrated
control system, significant hardware and
installation cost savings can be achieved. Valve
accessories such as limit switches and position
transmitters can be eliminated because this
information is available via the HART
communication protocol. In addition, an integrated
4‐20 mA position transmitter or limit switch option
is available.
n Improved Maintenance Decisions—Digital
communication provides easy access to the
condition of the valve. Sound process and asset
management decisions can be made by analysis of
valve diagnostic information through ValveLink
software, DD's, or DTM's.

Safety Certification
The functional safety assessment was performed to
the requirements of IEC 61508: ed2, 2010, SIL3.
The DVC6200 SIS digital valve controller, in the
de-energize to trip (DETT) or energize to trip (ETT)
configuration, meets the systematic integrity
requirements of SIL 3.
The DVC6200 SIS position monitor, in the position
transmitter or limit switch configuration, meets the
systematic integrity requirements of SIL 2.

Valve Diagnostics
The DVC6200 SIS digital valve controller provides a
broad and deep portfolio of valve diagnostic
capabilities. Whether the 475 Field Communicator is
used to check for valve alerts and operational status, or
ValveLink software is used for comprehensive
diagnostic test and analysis, the tools are easy to use.
Valve diagnostic tests enable condition and
performance monitoring of the entire valve assembly not just the digital valve controller. Results are
displayed graphically, with severity indicated by a
red/yellow/green icon. A detailed description of the
identified issue as well as suggestions for
recommended actions are provided.
In the event that the DVC6200 SIS is commanded to
trip, diagnostic data can be gathered automatically to
be used for troubleshooting.
Solenoid Valve Health Monitoring
If a solenoid valve is installed between the DVC6200
SIS pressure output and the actuator, as shown in
figure 3, the final control element assembly can be
configured to verify the operation of the solenoid valve
during online operation. In single-acting actuator
applications, the “unused” output port of the
DVC6200 SIS can be piped such that the pressure
downstream of the of solenoid valve is measured.
When the solenoid valve is pulsed, the DVC6200 SIS
can sense the momentary pressure drop across the
solenoid valve. The solenoid should be pulsed long
enough to detect a pressure drop across the solenoid
valve, but not so long that it affects the travel of the
final control element. This not only increases the
availability of the solenoid valve during a safety
demand, but also enhances the reliability of the SIF
(Safety Instrumented Function) loop.
